Its goals are explicit: be easy to distribute as a single binary, be extensible with custom formatters, and be usable as a library foundation for teams that need a customized YAML formatter. ### プロジェクトの歴史 The repository was created on 2022-08-10. The README describes the project as an extensible formatter rather than only a fixed style tool: users can run the `yamlfmt` command, install it as a pre-commit hook, use a container image, or build on the library APIs. The project grew around formatter backends and configuration. The default `basic` formatter serializes YAML through a fork of gopkg.in/yaml.v3, while the `kyaml` formatter targets Kubernetes YAML style. The docs also record caveats around YAML directives, anchors, aliases, line breaks, and line-length behavior, showing the practical complexity behind YAML formatting. ### 採用の歴史 yamlfmt has a broad package-manager footprint in the supplied data, including Homebrew, Nix, apk, pacman, and Scoop. Its README also presents Go installation, release binaries, pre-commit integration, and a container image, which fits modern developer-tool adoption through local hooks and CI checks. The repository lives under the Google organization but the README states that it is not officially supported by Google and is maintained primarily by an individual maintainer in spare time. That makes it an interesting case where a high-visibility org namespace helped adoption of a still-community-paced developer tool. ### 使われ方 Basic usage is `yamlfmt x.yaml y.yaml ...` or `yamlfmt .`, where directories are searched recursively for `.yaml` and `.yml` files. The `-dstar` mode enables doublestar glob matching, and `-lint` supports CI workflows that check formatting without rewriting files. Configuration is discovered from a `-conf` flag, the working directory, ancestor directories, or a system config directory. Supported config filenames include `.yamlfmt`, `yamlfmt.yml`, `yamlfmt.yaml`, `.yamlfmt.yaml`, and `.yamlfmt.yml`. ### パッケージ好きにとっての重要性 yamlfmt is package-nerd significant because it packages the messy YAML-formatting problem as a distributable Go binary with docs for hooks, containers, global config, and release artifact verification. It also represents the split in YAML tooling between generic style normalization and domain-specific formats such as Kubernetes KYAML, a distinction that matters to maintainers choosing formatter defaults for large repositories. ### タイムライン - 2022-08-10: GitHub repository created. - 2020s: Project goals documented around single-binary distribution, custom formatter extension, and library use. - 2020s: Configuration discovery documented across local project files, ancestor search, and platform config directories. - 2020s: README documented pre-commit, container, and CI usage patterns. ### Related projects - Related projects and technologies include gopkg.in/yaml.v3, Kubernetes KYAML, pre-commit, bmatcuk/doublestar, cosign, and container-based CI runners. ### ソース - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
